Who has the best suggestion for programming your PCM?

[LuvAndCamaro]

I have a 2000 Z28 that I have just started modifying. I have changed the air lid, added a ported MAF, pacesetter headers, ORY, hi-flow cat, no muffler, and 17x9.5 ZR1 wheels with 315/35 tires. I am looking to change the gears to 3.73 and adding a 3300 stall soon but I need a state inspection before that and my SES light is on. I really need to reprogram the PCM to handle these changes but am not sure of where to go. Any help out there?

Thanks
